ANDREIV CAMPBELL, OF BROOKLYN, ASSIGNOR TO JOHN MOLOUGHLIN, OF-NEW YORK, N. Y.

AND EDMUND SH ELL OR COVER FOR PRINTERS ROLLERS.

SPECIFICATION forming part of Letters Patent No. 294,438,'dated March 4, I884.

Application filed July 30, 1883. (No model.)

To all whom itmay concern Be it known that I, ANDREW CAMPBELL, a citizen of the United States, residing at Brooklyn, Kings county, New York, have invented certain Improvements in Shells or Covers for PrintersRollers, of which the following is a specification. p

Rollers for the use of printers have been provided with covers of leather. It is to this class of rollers that my present invention relates. Heretofore, so far as I am aware, these leather covers have been stitched into the form of a flexible tube and turned, and then drawn over the yielding elastic core; or it has been,

proposed to make the core of some substance capable of being melted, and to pour it into said tubular cover While the latter is held in a tubular mold.

My object'is to produce a stiff tubular shelllike cover of leather, that may be made and sold as an article of manufacture; and 'in my construction I also seek to avoid the stitching, which, when the leather wears away, appears at the surface, and to provide a protecting film that will prevent the oils and solvents of the ink from penetrating through the leather to the-core and injuring the same. quite important when the core is of some substance that will be liable to injury from this causeas rubber, for example.

In carrying out my invention Itake aformer, preferably of wood and sectional, in the nature of a cylinder equal in diameter to the core of the roller. On this I wrap a strong fabric, preferably of linen, although muslin or This wrapping I coat with hot'glue, and then apply the leather designed to form the cover of the roller.

This leather is cut to the exact size to fit, prefera-bly beveled at the edges to lap a little, and these edges are glued to hold the leather in place. It may be temporarily wrapped exte- The shell thus formed is then slipped off the former, and is ready to receive the core. The glue imparts sufficient stiffness to the shell to prevent its distortion, and it also, being insoluble in the oils and solvents of the ink, serves to protect the core. The linen or other fabric crosses the joint where the edges of the leather abut, and makes a sufficiently strong joint.

This is proved form, and Fig. 2 is a cross-section of the same. Fig. 3 is aview designed to illustrate the spiral wrapping of the linen or other lining fabric on the former.

A represents the leather covering, the edges of which are by preference made to lap a little, as at a in Fig. 2.

B is the linen lining, which I prefer to apply to the former by wrapping it spirally around the same from end to end, as illustrated in Fig. 3.

G is the former, which may be a simple cylinder of wood, or sectional, as preferred.

In order to form a stiffened margin for the shell or tubular cover, I prefer to insert in it at the end a band, I), formed, by preference, of several coils or turns of wire. The linen or other lining fabric is folded over theband outwardly and glued. In order that this band shall not, owing to its thickness, produce a ridge by raising up the leather, I charnfer or cut away the latter, as at 0, so as to leave room for said band.

In applying the band I) the wire may be wrapped over the lining on the former O, and the margin of the fabric B turned over and glued down on said band.

These shells may be made and sold as an article of manufacture and sale, and they may be applied to their cores in any way desired as, for example, the shell may be slipped into the ordinary mold, the roller-stock set in place, and the usual roller-composition melted and poured in; or it maybe slipped over arubber or other core.

In order that the leather cover A may be gathered and drawn down to the roller-stock with a draw-string or thong, so as to protect the ends of the composition, I usually allow the leather to extend beyond the band Z2, as

l 2. As a new article of manufacture, a shell to form the cover of a printers1'oller,c0mprising an exterior cover of leather, cut away at c, an inner lining of linen or other like fabric glued to the inside of the leather, and the band I), secured to the inside of the tubular shell at its end, substantially as set forth.

In witness whereof I have hereunto signed 15 my name in the presence of two subscribing Witnesses.

ANDREW CAMPBELL.
